Haematopodin is the more stable breakdown product of
Haematopodin B.
Both compounds are found in the mushroom ''
Mycena haematopus'', although haematopodin only occurs in trace amounts in fresh
fruit bodies
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cyc ...
. Similar
pigments (with the 1,3,4,5-tetrahydropyrrolo
,3,2-''de''uinoline structure), known as
batzellins and
damirones, have been found in
sea sponges.
A
chemical synthesis for haematopodin was reported in 1996. Key steps in the synthesis involved the
addition
